2014-04-04ARM: OMAP2+: remove pdata quirks for displaysTomi Valkeinen
Remove pdata quirks for the displays on boards that are now supported properly with DT. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Acked-by: Tony Lindgren <tony@atomide.com>
2014-03-19ARM: OMAP2+: add omapdss_init_of()Tomi Valkeinen
The OMAP display architecture requires a bunch of platform devices which are not created via .dts (for now). We also need to pass a few function pointers and the DSS hardware version from the arch code to omapdss driver. This patch adds omapdss_init_of() function, called from board-generic at init time, which handles those tasks.

2013-11-26ARM: OMAP2+: dss-common: change IGEP's DVI DDC i2c busJavier Martinez Canillas
IGEP's DVI connector's DDC pins are connected to OMAP's third i2c bus. When booting with Device Trees the requested bus number is set to -1 which means that the bus number should be dynamically assigned. So the third i2c bus has 2 has a bus number. Since now only DT booting is supported for IGEP boards after commit 06ff74fd ("ARM: OMAP2+: remove legacy support for IGEP boards"), the i2c bus number has to be changed.

2013-10-09ARM: OMAP2+: pdata-quirks: add legacy display init for IGEPv2 boardJavier Martinez Canillas
IGEPv2 board has both an DVI and TFP410 video interfaces but DSS support for DeviceTree has not yet landed in mainline so is necessary to init the displays using legacy platform code.

2013-08-28ARM: OMAP: 4430SDP: remove picodlp device dataTomi Valkeinen
4430SDP board has an option for a PicoDLP mini-projector. PicoDLP cannot be used at the same time as the second LCD, and there are GPIOs that need to be set/unset when changing the used display. Managing that kind of board specific setup is not simple without board file callbacks. As only some 4430SDP boards actually have the PicoDLP installed, and 4430SDP boards are not that common in the first place, let's remove PicoDLP data from the board file.

2013-08-28ARM: OMAP: dss-common: use new display driversTomi Valkeinen
Use the new display drivers for OMAP4 Panda and OMAP4 SDP boards. The new OMAP display drivers were merged for 3.11, and we can now change the board files to use the new ones and phase out the old ones. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Acked-by: Tony Lindgren <tony@atomide.com>

2013-08-02ARM: OMAP: dss-common: fix Panda's DVI DDC channelTomi Valkeinen
Panda's DVI connector's DDC pins are connected to OMAP's third i2c bus. With non-DT, the bus number was 3, and that is what is used in the dss-common.c which contains the platform data for Panda's DVI. However, with DT, the bus number is 2. As we now only have DT boot for Panda, we have to change the bus number to make DVI EDID read operational.

2013-04-04arm: dss-common: don't use reset_gpio from omap4_panda_dvi_deviceArchit Taneja
gpio reset info is passed to the tfp410 panel driver via the panel's platform data struct 'tfp410_platform_data'. The tfp driver doesn't use the reset_gpio field in the omap4_panda_dvi_device struct. Remove this field. Signed-off-by: Archit Taneja <archit@ti.com> Cc: Tony Lindgren <tony@atomide.com>
2013-04-04arm: omap: dss-common: use picodlp panel's gpio handlingArchit Taneja
The dss-common file currently requests gpios required by the picodlp DPI panel on the 4430sdp/blaze board. It also requests DISPLAY_SEL_GPIO and DLP_POWER_ON_GPIO gpios which are board specific gpios to switch between lcd2 panel and picodlp, and setting intermediate power supplies for picodlp respectively. These gpios are toggled through platform_enable/disable functions called by the picodlp driver. Remove the gpio requests for the gpios which are already requested by the panel driver, and remove the platform callback functions and set the platform specific gpios in such a way that lcd2 panel is selected for the LCD2 overlay manager and the power supplies for picodlp are disabled. Note: We need to revisit this so that we can enable and switch to picodlp if that's the only panel driver available for the LCD2 overlay manager.

2013-04-03OMAPDSS: panels: keep platform data of all panels in a single headerArchit Taneja
Structs for platform data of omapdss panels are found in headers in the 'include/video/' path. Board files populate these structs with platform specific values, and the panel driver uses these to configure the panel. Currently, each panel has it's own header in the above path. Move all the omapdss panel platform data structs to a single header omap-panel-data.h. This is useful because: - All other omapdss panel drivers will be modified to use platform data. This would lead to a lot of panel headers usable only by omapdss. A lot of these platform data structs are trivial, and don't really need a separate header. - Platform data would be eventually removed, and platform information would be passed via device tree. Therefore, omapdss panel platform data structs are temporary, and will be easier to remove if they are all in the same header. - All board files will have to include the same header to configure a panel's platform data, that makes the board files more consistent.

2012-12-17ARM: OMAP2+: Drop plat/cpu.h for omap2plusTony Lindgren
The cpu_is_omap macros are now local to arch/arm/mach-omap2 in soc.h and plat/cpu.h can finally be dropped for omap2+. Thanks everybody for help with fixing the drivers. Note that we can now also remove the unused plat/cpu.h from smartreflex.c and isp.c as they will cause compile errors with ARCH_MULTIPLATFORM enabled.

2012-11-07OMAP: omap4sdp: move display init from board file to dss-common.cTomi Valkeinen
Device tree support for omapdss is still some way in the future. In an effort to get a minimal DSS support for DT enabled kernel on selected OMAP4 boards, we'll go for a temporary solution: We will call the same non-DT omapdss setup code for OMAP4 SDP and Pandaboards from board-generic.c, thus enabling DSS for those boards. This patch moves the display setup code from board-4430sdp.c to dss-common.c. dss-common.c will be called by the board-4430sdp.c when running on non-DT kernel, and by board-generic.c when running on DT enabled kernel.
